The MOST accurate pH Standards available anywhere now color-coded for convenience
Traceable® pH Standards, Certified Reference Materials, are 100% compatible with all instruments and probes. Accuracy for the Traceable® Buffer at 25°C is ±0.010 pH—the most precise available.
Certified Reference Materials meet Federal/State/local agencies’ strictest mandates and deliver exact calibration results for any pH meter.
Certification documentation supplied for every Traceable® Certified Reference Material
A2LA ISO/IEC 17025:2005 (1750.01) (Calibration Laboratory) and ISO 17034 (formerly ISO Guide 34) (Certified Reference Material Producer) provide highest achievable levels of product production, documentation, and accuracy. Additional certifications include ISO 31 (content) and ISO 35 (statistical analysis). ISO 9001 ensures that world-class product standards for Materials are always met. Each value is provided in a corresponding color for proper identification during testing.
To assure accuracy an individually serial-numbered Traceable® Certificate is supplied to indicate traceability to standards provided by NIST (National Institute of Standards and Technology) and/or a National Standards Laboratory.
